The viewers described in the above documents have a problem that it is difficult to carry them compactly together with recent miniaturized and thinned portable devices because each plate-shaped portion is thick and the hinge structure is also large. Further, although each of the above viewers has a folding structure, since the dimensions of each part are fixed, it can be applied only to a specific display device, and there is a problem that it lacks versatility.

Therefore, the present invention solves the above-mentioned problems, and the problems can be carried compactly together with a miniaturized and thinned mobile device, and can be easily applied to various mobile devices and have high versatility. It is to provide a viewer.

In order to solve the above problems, the viewer for a portable device of the present invention has a thin plate-shaped optical substrate having a thin plate-shaped substrate portion having an insertion piece portion and a lens portion foldably connected to the outer edge of the substrate portion. It is characterized in that the substrate portion and the optical portion are configured to be mutually foldable, and the entire portion is formed in a plate shape in the folded state.

It is desirable that the portion is insertable into the receiving portion.

According to the present invention, an insertion piece portion is inserted (inserted) into a receiving portion of a plate-shaped member such as a card holder provided on the inner surface of a cover portion formed in a case or the like for accommodating a mobile device main body. It can be easily and quickly installed, and it can be folded compactly in a posture in which the substrate portion is arranged on the inner surface provided with the receiving portion of the cover portion, and the whole can be made into a plate shape, so that it can be easily and quickly installed in a case or the like. Can be stored compactly. In addition, since the optical part that can be bent with respect to the substrate part can be easily faced to the display screen of the mobile device body with the cover part open, the display screen can be easily visually recognized through the lens part. Will be possible. At this time, the viewer for mobile devices is attached by inserting the insertion piece portion into the receiving portion, and the optical portion is foldably connected to the substrate portion attached to the cover portion. The height, position, angle, etc. can be easily adjusted. In addition, this makes it possible to provide versatility that can be applied not only to a specific mobile device but also to various mobile devices.

In the present invention, the insertion width of the insertion piece portion is preferably smaller than the acceptance width of the receiving portion. According to this, it becomes possible to perform focus adjustment and position adjustment without removing it from the cover portion. In this case, it is desirable that the insertion piece portion is partially formed in the substrate portion by cutting the substrate portion. According to this, since the peripheral edge portion of the substrate portion can be provided at least a part around the insertion piece portion, the substrate portion and the optical portion can be connected even at the outer edge around the insertion piece portion. Even if the thickness is reduced as a whole, the required rigidity as a viewer can be easily secured.

In the present invention, it is a thin plate-shaped support portion arranged along the inner surface of the substrate portion in the folded state, and is foldably connected to the mounting piece portion fixed to the substrate portion and the mounting piece portion. It is preferable to further include the support portion having an overhanging portion that can be arranged between the optical portion and the display screen by rising from the substrate portion. In this case, when the insertion piece portion is configured to protrude from the thickness range of the substrate portion toward the cover portion by a notch provided in the substrate portion, the mounting piece portion is formed on the substrate portion. A portion of the substrate portion other than the insertion piece portion (for example, in a manner in which the insertion piece portion is arranged on the opposite side of the cover portion with respect to the insertion piece portion within the plane range of the insertion piece portion in the above. , It is desirable to be fixed to the peripheral portion). At this time, it is more desirable that the mounting piece portion is fixed to the portion in such a manner that it fits snugly within the plane range and the thickness range.

In the present invention, it is preferable that the optical portion is provided with a locking structure for locking the overhanging portion of the support portion. It is desirable that this locking structure is formed at the tip end portion of the optical portion opposite to the connection edge with respect to the substrate portion. Further, it is more desirable that the locking structure is formed at the tip edge portion formed so as to be mountain-foldable along the parallel line of the tip portion of the optical portion.

Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, the structure of an embodiment of a viewer for a mobile device according to the present invention will be described with reference to FIGS. 1 to 6. The viewer 13 for a mobile device is made of a thin plate-like sheet material made of paper, a resin plate, a metal plate, or the like, and is configured to be foldable as a whole. The sheet material is preferably made of a flexible material as long as it has rigidity that can autonomously hold the assembled state described later. The thickness of this sheet material is preferably 50 to 2000 μm, and particularly preferably 200 to 1000 μm. Further, the size of the viewer for mobile devices when folded is preferably in the range of 50 mm to 100 mm in length and 70 mm to 180 mm in width for smartphones. In particular, within the above range, it is desirable that the length and width are 65 mm × 130 mm or larger.

The viewer 13 for a portable device includes a thin plate-shaped rectangular substrate portion 131 and a thin plate-shaped rectangular optical portion 132 foldable and connected along a mountain fold line 131t on one long side of the substrate portion 131. , It is fixed to the substrate portion 131 and can be arranged so as to overlap the inner surface of the substrate portion 131, and a part thereof can be raised (raised) by folding along the valley folding line 133t. It is provided with a formed thin plate-shaped and rectangular support portion 133. The rectangular shape of each part is an example, and each part may be formed in a thin plate shape, and may be formed in a plane shape other than the rectangle, for example, an elliptical shape. However, it is desirable that the shape is extended in a predetermined direction (horizontal direction in the illustrated example).

The substrate portion 131 includes a substantially U-shaped cut line 131s inside its planar shape, and includes a rectangular insertion piece portion 131a formed by the cut lines 131s to be one size smaller than the substrate portion 131. Further, the portion other than the insertion piece portion 131a is the peripheral edge portion 131b. In the illustrated example, the peripheral edge portion 131b is provided over the entire circumference of the insertion piece portion 131a. The insertion piece portion 131a is not limited to a rectangular shape, but may be a thin plate-shaped portion having a tongue shape as a whole and being insertable into a receiving portion such as a card holder. Further, as shown in the illustrated example, the cut line 131s need not be formed so as to form the entire insertion piece portion 131a except for the connecting portion. For example, one or two sides (length) of the substrate portion 131 need to be formed. The insertion piece portion may be provided by using the side (side or short side) and forming a cut line only in the remaining portion. However, in this case, the portion of the substrate portion 131 other than the insertion piece portion 131a does not have a shape over the entire circumference like the peripheral portion 131b, for example, the square frame shape of the illustrated example. Further, the width of the substrate portion 131 may be narrowed as it is, or one side portion of the substrate portion 131 may be used as it is as the insertion piece portion 131a (in this case, when the peripheral edge portion 131b is not clearly partitioned or inserted. In some cases, the portion that is not used can only be grasped as the peripheral portion 131b). The inner surface of the substrate portion 131 is preferably opaque, has a dark color such as black, and has a low light reflectance.

The optical unit 132 includes a pair of lens portions 132a and 132b inside its planar shape. These lens portions 132a and 132b are not particularly limited, but preferably have a rectangular or square planar shape. Further, it is preferably a Fresnel lens. For example, it is desirable to have a magnifying glass function used for a seat loupe, a seat lens (card lens), or the like. With such lens portions 132a and 132b, an image of a display screen described later can be visually recognized with the eyes away from the optical portion 132. The distance of the eyes from the optical unit 132 that focuses on the display screen is preferably within 20 cm. Further, in the optical unit 132, the lens portions 132a and 132b are integrated by the frame portion 132c. In the illustrated example, the frame portion 132c is formed in a frame shape at the upper and lower sides of the portion between the pair of lens portions 132a and 132b and the respective lens portions 132a and 132b. The frame portion 132c is preferably opaque, and particularly preferably has a low light reflectance such as a dark color such as black.

The optical unit 132 is provided with a tip edge portion 132d configured to be bendable along the mountain fold line 132t. In the illustrated example, the tip edge portion 132d is a portion partitioned by the mountain fold line 132t parallel to the long side of the optical portion 132. A notch 132e, which is a locking structure, is formed in the central portion of the tip edge portion 132d. As described above, by providing the tip edge portion 132d connected to the lens portions 132a and 132b (or the frame portion 132c around the lens portion 132c) of the optical portion 132 via a crease, the optical portion 132 is provided in the longitudinal direction ( The rigidity in the left-right direction in the drawing can be increased, and the overall rigidity of the viewer 13 for a portable device can be increased by locking the tip edge portion 132d to the overhanging portion 133b. Therefore, since the thickness of the sheet material can be reduced by that amount, it is possible to further make the sheet material more compact (thinner) at the time of folding. Also, for the same reason, a more flexible material can be used as the sheet material, so that it can be configured so that it can be slightly deformed by increasing the flexibility of the assembled state, or it can be folded according to the situation of the storage place. It becomes easier to adapt the condition.

The support portion 133 includes a mounting piece portion 133a fixed to the substrate portion 131, and an overhanging portion 133b configured to be foldable with respect to the mounting piece portion 133a at a valley fold line 133t. Here, the mounting piece portion 133a is fixed to the peripheral edge portion 131b of the substrate portion 131 in a state of being arranged within the plane range 131p partitioned by the cut line 131s and within the thickness range 131q of the substrate portion 131. Is preferable. At this time, the mounting piece portion 133a is arranged on the inner surface side opposite to the cover portion 12b with respect to the insertion piece portion 131a. The plane range 131p is the range of the opening that appears when the insertion piece portion 131a is deformed so as to protrude from the thickness range of the substrate portion 131. Further, the thickness range 131q is a range of spaces within the thickness range of the substrate portion 131 (peripheral portion 131b) existing in the range of the opening. As a result, the insertion piece portion 131a is in a state of protruding toward the cover portion 12b from the thickness range 131q along the peripheral edge portion 131b as shown in FIG. 6 by arranging the mounting piece portion 133a. Be maintained. In particular, as shown in the illustrated example, it is desirable that the mounting piece portion 133a is fixed to the peripheral edge portion 131b in such a manner that it fits snugly in the plane range 131p and the thickness range 131q. The mounting piece portion 133a is attached to the peripheral edge of the substrate portion 131 by welding or bonding through a mounting material such as a fixing tape (not shown), or by direct welding or bonding to the inner edge of the peripheral peripheral portion 131b around the plane range 131p. It is fixed to the portion 131b. The inner surface of the mounting piece portion 133a is preferably opaque, has a dark color such as black, and has a low light reflectance.

As shown in the illustrated example, the overhanging portion 133b is preferably formed in a thin plate shape so as to partition the lower region of the drawing that can be seen through the pair of lens portions 132a and 132b. In the illustrated example, the overhanging portion 133b is formed in a flat plate shape having an upper edge portion along the frame-shaped portion 132c between the pair of lens portions 132a and 132b, and is displayed as it is from the upper edge portion to the lower side of the drawing, which will be described later. It extends downward so as to have the same width toward the screen 11a, and has a lower edge portion parallel to the upper edge portion. When functioning as a partition plate in this way, both sides of the overhanging portion 133b are preferably opaque, such as the inner surface of the substrate portion 131, the frame portion 132c, and the inner surface of the mounting piece portion 133a. It is desirable that the color is dark, such as black, and the light reflectance is low. The overhanging portion 133b does not need to be in contact with both the lower surface of the optical unit 132 and the surface of the display screen 11a in the assembled state during use, which will be described later, and is configured to be slightly separated from both of them. Even if it is, it may be possible to substantially function as a partition plate.

In the illustrated example, the overhanging portion 133b is configured to be able to support the illustrated lower surface of the frame portion 132c between the pair of lens portions 132a and 132b in the optical portion 132 by folding up from the mounting piece portion 133a. Further, the overhanging portion 133b is configured to be insertable into the notch 132e which is a locking structure provided in the tip edge portion 132d. The overhanging portion 133b is held by the tip edge portion 132d by being locked to the locking structure (cut 132e). A notch (locking structure) may be formed in the overhanging portion 133b together with the notch 132e or instead of the notch 132e. Further, the locking structure is not limited to the above-mentioned notch, and a surface fastener structure, a snap stopper structure, or the like may be used.

FIG. 1 shows a state in which the viewer 13 for a mobile device is assembled as described above. Here, in FIG. 2, the support portion 133 composed of one sheet piece is attached to another sheet piece in which the substrate portion 131 and the optical portion 132 are integrally provided, whereby the viewer for a mobile device is used. It is shown that 13 is assembled. From the assembled state shown in FIG. 1, as shown in FIG. 3, when the notch 132e and the overhanging portion 133b are released from the locked state and the overhanging portion 133b is folded onto the inner surface of the substrate portion 131, as shown in FIG. become. After that, when the optical portion 132 is folded toward the inner surface of the substrate portion 131, as shown in FIGS. 5 and 6, the substrate portion 131, the optical portion 132, and the support portion 133 are overlapped with each other to form a plate-like folded state. Can be.

FIG. 7 shows the overall configuration of the portable device 10. The mobile device 10 is connected to a mobile device main body 11 having a display screen 11a, a mounting portion 12a on which the mobile device main body 11 is mounted, and a mounting portion 12a, and is configured to be openable and closable with respect to the display screen 11a. A case 12 having a portion 12b and a case 12 are provided. As shown in FIG. 9, receiving portions 12c, 12d, and 12e that can accept thin plate-shaped members such as cards are provided on the inner surface of the cover portion 12b of the case 12. The insertion piece portion 131a of the viewer 13 for a portable device can be inserted into the receiving portions 12c to 12e. Further, by inserting the insertion piece portion 131a into the receiving portions 12c to 12e, the viewer 13 for a portable device is mounted on the inner surface of the cover portion 12b. At this time, since the insertion width Wi of the insertion piece portion 131a is smaller than the reception width Wr of the receiving portions 12c to 12, the viewer 13 for the portable device is attached to the cover portion 12b (that is, to the portable device main body 11). While maintaining it, it can be moved in the vertical direction shown in the figure. The illustrated vertical direction is a direction in which the lens portions 132a and 132b approach and separate from the display screen 11a in the assembled state.

When the viewer 13 for a mobile device is attached to the cover portion 12b, as shown in FIG. 8, the insertion piece portion 131a on the outer surface of the substrate portion 131 is separated from the peripheral portion 131b and the mounting piece portion 133a, and the receiving portion 12c Insert into ~ 12e. At this time, the mounting piece portion 133a is arranged inside the plane range 131p and the thickness range 131q in which the insertion piece portion 131a is formed, so that the insertion piece portion 131a is on the outer surface of the substrate portion 131 as shown in FIG. Since the protruding state is maintained, the insertion piece portion 131a can be easily inserted into the receiving portions 12c to 12e when the viewer 13 for a portable device is attached.

FIG. 10 shows a state in which the viewer 13 for a mobile device attached as described above is assembled to form a mode when used. In the present embodiment, when the VR images 11L and 11R are displayed on the display screen 11a of the mobile device main body 11, the stereoscopic image can be seen by visually recognizing through the lens portions 132a and 132b. Further, even if it is not a VR image, the image can be magnified by viewing the image of the display screen 11a through the lens portions 132a and 132b. Therefore, it is possible to confirm fine characters and details of a fine image. Here, the cover portion 12b and the substrate portion 131 (peripheral portion 131b) can be visually recognized through the lens portions 132a and 132b while being sandwiched by hand. For example, the left and right hands grip the portions on both the left and right sides where the cover portion 12b and the substrate portion 131 overlap. At this time, the overhanging portion 133b of the support portion 133 has a function of supporting the optical portion 132 from below, and also functions as a partition plate for dividing the field of view of the left and right lens portions 132a and 132b. It is not necessary to support the overhanging portion 133b in a state of being in direct contact with the optical portion 132 (particularly, the frame portion 132c between the pair of lens portions 132a and 132b as shown in the illustrated example) as shown in the illustrated example. , It may be arranged between the optical unit 132 and the display screen 11a. This may prevent the substrate portion 131 and the optical portion 132 from being significantly deformed when the viewer 13 for a portable device is used. Further, the overhanging portion 133b can also be used as a gripping portion for holding the viewer 13 for a mobile device. In this case, the viewer 13 can be gripped with one hand.

In the present embodiment, the viewer 13 is illustrated as shown by an arrow F within a range in which the insertion width Wi of the insertion piece portion 131a can be moved within the reception width Wr of the reception portions 12c to 12e with respect to the cover portion 12b. It is configured to be movable in the vertical direction. Therefore, since the distances of the lens portions 132a and 132b with respect to the display screen 11a can be adjusted, the focus can be adjusted and the insertion piece portion 131a can be moved in the insertion direction (left-right direction in the drawing), which is good. Can be used in a normal state. Further, the substrate portion 131 and the optical portion 132 can change the bending angle at the fold (mountain fold line 131t) to some extent as shown by the arrow R. Therefore, by changing the standing angle of the cover portion 12b with respect to the display screen 11a, it is possible to adjust the plane position of the lens portions 132a and 132b on the display screen 11a while maintaining the parallelism of the optical portion 132. is there. At this time, if necessary, the locking depth between the locking structure (cut 132e) and the overhanging portion 133b may be made shallower or released. It is also possible to use the optical unit 132 at an angle with respect to the display screen 11a. Further, the locking structure is not provided on the optical portion 132, but is provided, for example, on the mounting portion 12a of the case 12 so as to project upward from the outer edge portion on the side opposite to the inner surface of the cover portion 12b. The locking band may be configured to lock the lower tip of the overhanging portion 133b.

Further, in the present embodiment, the height, position, angle, etc. of the lens portions 132a and 132b of the viewer can be easily adjusted as shown by the arrows F and R depending on the aspect of the mounting structure to the cover portion 12b, so that the versatility is improved. Since it can be enhanced, it can be used not only for a specific mobile device main body 11 but also for various mobile devices. Further, since the viewer 13 for a mobile device can be attached / detached by inserting / removing the insertion piece portion 131a and the receiving portions 12c to 12e of the cover portion 12b, the attachment / detachment work can be performed extremely easily and quickly. Further, as shown in FIGS. 1 to 5, the transition operation between the folded state and the assembled state can be easily and quickly performed with the viewer 13 for a mobile device attached to the cover portion 12b.

Although the viewer 13 for the embodiment device of the present embodiment has a simple structure as described above, it is lightweight, thin, and flexible, so that it has an advantage that it is extremely easy to use and can be manufactured at low cost. Further, since the perspective space between the lens portions 132a and 132b and the display screen 11a is open to the outside, airtightness cannot be obtained, but the structure can be simplified accordingly, so that the weight can be reduced. It is easy to make it thinner and can improve storage (compactness).

The viewer for mobile devices and the mobile device of the present invention are not limited to the above-mentioned illustrated examples, and it goes without saying that various modifications can be made without departing from the gist of the present invention. For example, in the illustrated example, the overhanging portion 133b is configured to have both a support function and a partition function for the optical unit 132, but it is also possible to have only one of them. Further, the overhanging portion 133b can be designed not as a support function for the optical portion 132 but as a device that abuts on the display screen 11a to hold the entire viewer on the screen, or as a gripping portion of the viewer. For example, it may be configured to project downward from the optical unit 132 so as to easily come into contact with the display screen 11a. Further, the viewer for a mobile device can be used independently from the main body of the mobile device or the case.
